Abstract

The application discloses an octyl p-methoxycinnamate degrading bacterium, Pseudomonas sp. Pseudomonas OMC5, the preservation information of which is as follows: a preservation unit is Guangdong Microbial Culture Collection Center (GDMCC), a preservation date is November 25, 2025, a preservation address is the fifth floor of No. 59 building, Guangdong Microorganism Institute, 100, Middle Jianli Road, Guangzhou, a postal code is 510070, and a preservation number is GDMCC NO. 67353. The application separates Pseudomonas sp. Pseudomonas OMC5 with good degradation effect on octyl p-methoxycinnamate from sludge of a Guangzhou sewage treatment plant, and the Pseudomonas sp. OMC5 can be used for degrading and removing octyl p-methoxycinnamate. An economic and green method is provided for removing the new type of organic pollutants.
